How do we get rid of the letterbox on content

We have TV shows in our library.  They are all loading with letterboxes on our XBox (black bars around all 4 sides of the picture).  Is there a way to configure plex so that it fills the screen?

According to an earlier thread -  https://forums.plex.tv/topic/129571-xbox-360-app-playback-video-size-problem/- Plex Staff are aware of the issue, have been able to reproduce it and can't yet release an update to the Xbox App. (That may mean that haven't developed a fix yet or just that Microsoft has a long pipeline for pushing updates out.)

Hey ! Thank you for the answer !

Just a little up to maybe get a faster update on this concern (the only one for me but a critical one)
